You can also let students use the generator to practice skip-counting concepts. With the generator, you can make customized number charts and lists. This interactive tool allows children to explore a 100-chart or a teacher to illustrate various math concepts, such as even and odd numbers, multiples of 5 and of 10, and skip-counting by 2, 3, 4, 5, and so on. List of multiples of 3 (which numbers are colored yellow?)Ĭount from 1 to 100, every fourth number is colored yellow Multiples of 4 chart every fourth number is highlighted in yellowįill in odd numbers from 1 to 201 - 70% of the numbers are missing Multiples of 3 chart every third number is highlighted in yellow Tip: Generate several charts for children to fill in, because each time the numbers that are missing will be different.ġ00-chart - 70% of the numbers are missingġ00-chart - 70% of the numbers are missing even numbers are highlighted Scroll down the page to the generator if you want to customize the charts yourself.ġ00-chart - half of the numbers are missing

With the exception of the two top ones (which are static), they are randomly generated each time you click on the button. Tip: use a negative step to practice counting backwards.īelow you will find some common charts both in html and PDF format.

The charts can be made in html or PDF format (both are easy to print).Īnother feature is that you can highlight in yellow the boxes at certain intervals, which creates pretty skip-counting patterns. You can decide how much of the chart is pre-filled, the border color, skip-counting step, and so on. The calculator also indicates the nth prime for the first 1000 prime numbers.This generator makes number charts and lists of whole numbers and integers, including a 100-chart, for kindergarten and elementary school children to practice number writing, counting, and skip-counting. Prime Factors Calculator to verify that a number is prime. Hover your mouse over any number in the table to see the n th label as The prime number at the intersection of row 220 and column heading 3 is Prime = 1409. To find a prime number, say Prime, find row heading 220 and column heading 3 for 220+3=223. You can also denote the nth prime number with brackets as Prime, so: The n th prime number can be denoted as p n, so: There are 1,009 total prime numbers in the lookup table below.

The prime numbers table lists the first 1000 prime numbers from 2 to 8011.
